FF 41, xpinstall.signatures.required Causes NoScript Prompt

[therube]

FF 41, Nightly, about:config, Toggle xpinstall.signatures.required from 'false' to 'true' Causes a NoScript Prompt, "By disabling or uninstalling NoScript, you give up ALL protections provided by NoScript ...".


I happen to have a staged NoScript update if that could have any bearing?


Is it late? Yes.
Is that a NoScript Pref?


Oh, nevermind.
I see what's happening.

When I toggle the Pref from false to true, at that point FF automatically disables ALL unsigned extensions (& none of mine are signed) & when NoScript senses that disablement, it throws up its warning.
